Scale identifier systems and methods for generating a log of scale type and location in subterranean formations, and, more particularly, in wellbore tubing are provided. A method for scale identification may be provided. The method may comprise providing a first logging tool comprising a tool body, a neutron source coupled to the tool body, and detectors coupled to the tool body; providing a second logging tool for measuring deviations in inner diameter of a tubing in a wellbore; placing the first logging tool and the second logging tool into the wellbore; logging the interior of the tubing with the first logging tool and the second logging tool to generate data; and generating a log of scale location and type from the data.
